Company Profile
We specialize in intelligent motorization systems, delivering cutting-edge solutions for sunshading applications including tubular motors, curtain motors, and smart control systems.
With a fully integrated supply chain, we offer complete vertical manufacturing — from R&D to tooling, PCB assembly, and final product production — ensuring consistent quality and fast turnaround. Our R&D center houses over 50 engineers across disciplines: industrial design, mechanical and electronic engineering, embedded software, and intelligent control. This allows us to respond quickly to market needs with customized, high-performance solutions.
We operate a high-precision tooling workshop with CNC machining centers, EDM, and horizontal mills. Our SMT lines feature imported high-speed placement machines, robotic arms, and automated testing to guarantee ±1mm accuracy and high production efficiency.
Lean manufacturing and rigorous quality control are applied at every stage, delivering products that are reliable, scalable, and ready for global markets.
Since our founding in 2002, we have earned recognition as a National High-Tech Enterprise and were the first Chinese company to obtain full VDE certification for tubular motors. We hold multiple certifications, including TÜV, UL, CE, and CCC, and our motors are sold in over 100 countries worldwide.
Our commitment to innovation — including recent breakthroughs in AI-powered motors — continues to push the boundaries of smart automation.
Your trusted expert in vertically integrated, intelligent motorization solutions.
